Ultra-Lightweight
The ultimate like-it’s-not-even-there fit. Ultralight socks are knit from ultra-lightweight yarns, for our thinnest socks with the lowest in-shoe profile. With ultralight merino, you get all the benefits of wool socks — breathable, thermoregulating, odor-resistant — in a sock so low profile, you might forget it's there. These are socks you can run in for miles or ski in all day, durable and comfortable.
